The majority of apps that we cover under on App of the Day are either free or cost just a couple of quid so it's not often that we get the chance to write about an app that will set you back nearly fifty notes. Priced at £49.99, TomTom's satnav app isn't the cheapest or newsest app, but having just received an update with a very handy new new feature, it's got plenty on offer.

As well as the most up-to-date maps, the updated version of the app brings with it a useful new feature that means you can plan multiple stops in your route. This is particularly good if you're on a long drive and you need to plan a few breaks away from the wheel, or if you're on a trip that requires picking people up along the way. You can plan a journey with up to five stops, meaning that you don't have to plan each route separately - a first for a TomTom app.

Along with the updated features, you'll get all the usual stuff like the fastest traffic routes available (powered by HD Traffic), speed camera alerts, and daily free map updates. You can search for local shops and businesses and there are also plenty of places of interest pre-installed in case you're looking for somewhere to go on a day out.

Whats' more, you can take your pick from a selection of celebrity voices - including Homer Simpson, Darth Vader and C-3PO - which are available as in-app purchases for £3.49. You'll also be able to customise your app with various map colours and car symbols.

Although designed primarily for use with the iPhone, TomTom's app will also work with the iPad and iPod touch. However, it isn't supported on some of the earlier models (such as the first-gen touch) so make sure you check compatibility before you buy.
